Kathy, would you be kind enough to offer an explanation and/or source-citation of this idea? While the Mergenthaler Linotype process was not available until the 19th century, once Joh: Gutenberg adopted the Chinese concept of movable type a variety of means were used to carve or cast movable type, which could be used for any letter or ideogram in any written language. _http://en.wikipedia.org/wiki/Linotype_ (http://en.wikipedia.org/wiki/Linotype) _http://en.wikipedia.org/wiki/Movable_type_ (http://en.wikipedia.org/wiki/Movable_type) Even today a select number of artisans hand-set type for special printed works, some designing their own type faces "from scratch." Am I on the wrong track here? I would much appreciate the information. Good hunting to all, Judy Kathy Gunter Sullivan writes: A printed document of certain periods would have used the letters "u" and "v" interchangeably because of limitations of the printing press.
